Related Genotype: a/a Myo5ad/Myo5ad Mregdsu/MregdsuStrain Development
The mutation dilute suppressor (dsu) arose spontaneously in the dilute curly whiskers stock (CWD/Le JR284) at F16 in 1976 at the Jackson Laboratory. The mutation is observed only in dilute homozygotes (Myo5ad/Myo5ad). It is maintained by sibling matings homozygous for both dilute and dilute suppressor (Myo5ad Mregdsu/Myo5ad Mregdsu). It was cryopreserved in 1987 by mating homozygotes at F40. It was removed from the shelf at F92 in 2001.

| Molecular Note | Genomic PCR and DNA sequencing analysis showed the mutation is a deletion that spans the region from 11.1-kb upstream of the initiator methionine to intron 2. Northern and RT-PCR analysis demonstrated that no wild type transcript could be detected in the mutant animals. Western blot analysis of homozygous mutant melanocytes showed that it also is not expressed at the protein level. [J:94728] | ||

| General Note |
Mutations at the Myo5a locus lighten coat color through an abnormal morphology of melanocytes that causes uneven pigmentation of the hair shaft (J:11005). Most of these mutations also cause severe neurological defects; in some mutant forms, these defectslead to early death (J:12978), while in others life span is normal, but convulsions and loss of equilibrium occur after about four months of age (J:16915). Maltese dilution, as this mutation was originally called, is an old mutation of the mouse fancy. The blue-gray color of the hair produced by this mutation in nonagouti (a/a) mice is caused by clumping of the melanin pigment into a few large masses (J:12958). The melanocytes are misshapen, with fewer and thinner dendritic processes than wild-type melanocytes, and melanin granules are largely clumped around the nucleus (J:12970). Incorporation of tyrosine into melanin proceeds at a normal rate (J:12173), and the fine structure of the melanin granules is normal (J:5346). Cultured primary melanocytesfrom dilute homozygotes are normal in morphology but display clustering of melanosomes (J:37976). Griscelli disease (Chediak-Higashi-like syndrome, OMIM 214450) is a human autosomal recessive disorder whose symptoms include pigment dilution, immunodeficiency, and acute lethal lymphocyte and macrophage activation. Melanocyte malformation is characteristic of the pigment abnormality. The immunological abnormality includes absence of cutaneous hypersensitivity and impaired function of natural-killer cells. Griscelli disease resembles the dilute-lethal mouse mutant, except for the neurological disorder in the mouse. The locus for Griscelli disease colocalizes with the locus for myosin Va, which is mutated in at least some Griscelli patients. Griscelli disease is thus the homolog of mouse Maltese dilution (J:41253). The original Myo5ad mutation which identified the locuswas caused by insertion of an ecotropic murine leukemia virus (see Emv3) (J:6844, J:6587). All other mutations examined lack the virus. Reversions of Myo5ad to wild-type, which have been reported frequently, are caused by excision of the virusleaving exactly one long terminal repeat in place (J:7092). The virus is integrated into a noncoding region of the DNA (J:7751). | ||

| Supply Notes |
Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. |
